I don't actually have a script that does this, but it's very nice
behaviour, and I do use it from time to time.  I think we should have
another option for this, which would have options
OPT_EMULATE|OPT_BOURNE.  Note that zsh actually follows csh behaviour,
so this really should be OPT_BOURNE and not OPT_NONZSH.  (If you've
never heard of these options, you'll need to check the patch in article
1275.)

However, my original point stands.  ksh doesn't do brace expansion in
redirections.  We need to split up prefork() somewhere -- is there
another function that would be more appropriate to use in this case?
We need all expansions except for brace expansion and globbing, but
prefork() does everything except globbing.
